I think appending it to Osaka is fine if this method is about to be rolled out before Amsterdam. We had such precedent before with |

CL clients can make use of partial responses to exchange just the missing cells. This method allows the CL to request partial responses from the EL. Co-Authored-By: raulk <raul.kripalani@gmail.com>

CL clients can make use of partial responses to exchange just the missing cells. This method allows the CL to request partial responses from the EL.
This method is identical to getBlobsV2 but returns null entries if a blob is not available locally.
See https://ethresear.ch/t/gossipsubs-partial-messages-extension-and-cell-level-dissemination/23017 for context on cell level dissemination. See #674 for the prior version of this PR. That PR was closed to avoid adding a new requirement to Fusaka.
The changes here are currently in ./src/engine/osaka.md, but I'm happy to move them to a new file if folks prefer that. Maybe titled osaka-BPO-X.md where X is the BPO number we want these changes to be available in?
Implementing this method is not mandatory as CL clients can fallback to getBlobsV2. However for cell level dissemination to be useful, the EL needs to provide this method.
